This can be an RDP, SSH etc brute force. Assuming your host was compromised and was used for brute-forcing SSH nodes, and folks started reporting your IP to AbuseIPDB.

When folks report, they sometimes share the raw log, and this log has information related to the username it was attempting to login with.

Generating a list of the usernmaes used can provide insight into the sort of adversary that compromised your host.

It is the end user’s responsibility to obey all applicable local, state and federal laws.

$ cd abuse-insights
$ python abuse-insights.py

IF the IP address has been reported to Abuse IP DB in the past 90 days, & username data was avaialble, then output will be saved to a csv file – abuseIPDB_Username_Intel.csv.
